Neutron ML2/OVN packet fragmentation problems
Issue
- Packets are silently dropped by OVN if they are bigger than network MTU
- Packet drops when provider network MTU exceeds tenant network MTU
- OVN does not correctly fragment IPv4 packets when the MTU of the target network is smaller than the MTU of the source network
